Compiler extra flags

It is possible to add compiler flags for the entire build by wrapping toolchain binaries in script and hardlinking them.

How to install

Build the toolchain
Move original binaries from toolchain/out/bin to toolchain/out/bin_original
Copy wrapper.sh and setup_hardlinks.sh to toolchain/out/bin
Execute setup_hardlinks.sh
Edit compiler and linker flags (-O3 by default) in wrapper.sh to suit your needs
